With the space constraints and urgency required in a mobile push notification, every word counts. Leanplum has released a new report, "Push Notification Power Words". Based on a text analysis of more than 2.6 billion push notifications, the report identifies highly effective “power words” to help mobile marketers break through the noise and drive better app engagement.

In the report, they identify four key themes and associated power words for push alerts that lead to greater mobile engagement, from opens to conversions.

The report found that power words have substantial impact on critical app metrics. Publisher’s Clearing House (PCH), a gaming and sweepstakes company, launched a series of A/B tests experimenting with copy to drive more mobile growth and app revenue. PCH learned that the closer an app user is to churning, the more urgent a tone is needed to re-engage them. The results were impressive: PCH saw a 30 percent increase in retention.

Here is the list of the 120 "power words" but to completely understand the meaning and method to each word, check out the full report in the link below.
